A body condition score (BCS) rates how much fat a beef cow carries on a 1-to-9 scale, from 1 (emaciated) to 9 (very obese). It is the cheapest check you have on whether a winter feeding program is working, because condition at calving largely decides how quickly a cow breeds back. Oklahoma State University Extension aims for a score of 5 to 6 in mature cows at calving (Mississippi State University Extension says 5), and both aim for 6 in first-calf heifers. In a summary of six research herds in four states that Oklahoma State cites, about 60% of cows that calved at BCS 4 or less rebred in the next 60- to 90-day season, against about 80% at BCS 5 and about 90% at BCS 6 or more.
One score is worth about 7% of a cow’s weight at BCS 5, roughly 84 pounds on a 1,200-pound cow, and that weight is far cheaper to put on between weaning and the last months of pregnancy than after the calf is on the ground. That is why scoring belongs with your hay plan: score at weaning, sort the thin cows, test the hay, and you still have months to fix condition on forage.
Quick answer: Score beef cows 1 to 9 on fat cover. Aim for 5 to 6 in mature cows and 6 in first-calf heifers at calving. Score at weaning and again 60 to 100 days before calving, and use the months in between to put condition on thin cows with better hay or supplement; it is cheaper, and works better, than feeding them up after calving.
- The scale: 1 to 3 thin (ribs and backbone show), 4 borderline, 5 moderate (one or two ribs show), 6 to 7 fleshy, 8 to 9 fat.
- Quick check: if the last two ribs are easy to see, she is below 5; if you can see individual vertebrae, she is 3 or less (University of Wyoming).
- One score: about 7% of BCS-5 weight, 84 lb on a 1,200-lb cow (Oklahoma State); 70 to 140 lb depending on size and score (Mississippi State).
- Why it matters: about 60% rebred at BCS 4 or less, about 80% at 5 and about 90% at 6 or more, in the six-herd summary Oklahoma State cites.
- Hay: moving a 1,200-lb cow from 4 to 5 in the last 90 days of pregnancy takes a diet of about 59% TDN and 7.4% crude protein (Mississippi State). Hay testing in the low 50s for TDN will not do it alone (XES arithmetic).
A north central Kansas producer who rebred 85 two-year-olds in 2023 put the timing simply in February 2024: “Once she calves it is too late.”
This guide is for cow-calf producers who winter cows on hay or crop residue and want a simple, repeatable way to score them and act on the score. It covers the 1-to-9 chart, a three-step way to score, when to score, the targets and why they matter, how much weight one score represents, how hay quality decides whether thin cows can gain, fat cows, why cows lose condition, heifers and bulls, and a worksheet. It is not a ration and not veterinary advice; work out feeding amounts from your own hay test with a nutritionist or Extension specialist. Our guide to how much hay a cow eats covers intake, and how to read a hay test covers the numbers that matter here.
XES makes bale net wrap, and much of the hay it wraps is fed to beef cows in winter, so cow condition is where hay quality shows up. We read 865 posts from 223 archived AgTalk, HayTalk and TheFarmingForum discussions that mention body condition, condition scores or thin and fat cows (every post that mentions them, the post on either side, and every post in the 5 discussions with the topic in the title, out of 4,183 posts in those discussions; 203 of the discussions started in 2022 or later), and two readers coded about 300 of those posts as relevant to beef cow and heifer condition. Then we checked what producers said against Extension publications from Mississippi State, Oklahoma State, Virginia Tech, the University of Wyoming and North Dakota State.
The body condition score chart, 1 to 9
Beef cattle are scored from 1 to 9. Each score describes fat cover, not size: a big-framed cow and a small one can carry the same score at very different weights, and Oklahoma State’s fact sheet tells scorers to look past age, frame size, rib depth, body length, pregnancy and hair coat. The descriptions below follow Mississippi State’s Publication 2508 (2024 revision), with the visible-rib counts from Virginia Cooperative Extension’s publication 400-791.
| Score | Description | What you see and feel |
|---|---|---|
| 1 | Emaciated | No fat you can feel over the backbone, ribs or hooks; tailhead and ribs very prominent; physically weak. |
| 2 | Poor | Still emaciated, but tailhead and ribs less prominent; backbone still sharp to the touch. |
| 3 | Thin | All ribs easy to pick out, including the fore ribs; a little fat along the spine and over the tailhead. |
| 4 | Borderline | 3 to 5 ribs visible; the bumps of the backbone feel rounded rather than sharp; some fat over the ribs and hooks. |
| 5 | Moderate | 1 or 2 ribs visible; fat over the ribs feels spongy; fat you can feel on both sides of the tailhead. |
| 6 | High moderate | Ribs not visible; firm pressure needed to feel the backbone; some fat in the brisket and flanks. |
| 7 | Good (fleshy) | Very spongy fat over the ribs and around the tailhead; fat “pones” may be starting to form at the tailhead. |
| 8 | Fat | Very fleshy; backbone nearly impossible to feel; large fat deposits over the ribs and around the tailhead. |
| 9 | Extremely fat | Blocky and patchy; tailhead and hooks buried in fat; may move with difficulty. |
Two cautions from the same publications. Virginia notes that Bos indicus (Brahman-influenced) cattle may carry little fat over the ribs but deposit it over the hooks and pins, so look at the whole cow. And scales differ: the University of Wyoming’s guide points out that dairy cows are scored 1 to 5, and some of the Canadian beef producers we read also talk in fifths, so check which scale a number comes from before you compare it with a target. Producers mix them up, too; a north Florida poster weighing in on a new owner’s cows in August 2022 wrote:
"I wondered if you were talking about dairy BCS I think that is a 1-5 scale, or beef bcs I think is 1-10."

Beef cows are scored 1 to 9.
How to score a cow in three steps
The University of Wyoming’s 3-Step Body Condition Scoring Guide for Range Cattle (B-1294, 2016) reduces the chart to three looks, which is useful from a pickup or a feed alley:
- The last two ribs. If both are easy to see, the cow is below 5. If not, she is 5 or higher.
- The spine. If you can see individual vertebrae, she is 3 or lower.
- The shape between the hooks and pins. A shallow U is about a 6, a strong U a 5, a V shape a 4, a strong V a 3 and a very strong V a 2.
Long winter hair hides ribs, and a full rumen or a late pregnancy rounds out the belly. Mississippi State recommends feeling as well as looking when the hide is loose or the coat is thick: fat feels spongy, and bone with little cover feels sharp. Press over the ribs, along the backbone and on either side of the tailhead. Our own habit is to score from the side and from behind, the same way every time, and to compare a few cows together first when two people are scoring. Gut fill fools the eye in both directions, as a south central Iowa producer pointed out in May 2025 when a poster’s heifers looked worse after moving from dry hay to lush grass:
"We need pics to fully evaluate the body condition of your heifers but it’s possible to lose fill while gaining condition. You don’t see cattle that are being fed hard with a hay belly."
— t-boss, sc ia, May 2025 · AgTalk thread 1201596
Seeing the same cows every day hides slow change. Replying in January 2024 to a producer whose pairs were still on cornstalks and unweaned, another poster suggested a fresh pair of eyes:
"Their body condition should tell the story for you more than anything. ... If you see them every day its tough. My father in law would drive out in our cows once a week just for a different set of eyes on them"
— Iowa-beef, January 2024 · AgTalk thread 1142927
Weight alone will not tell you either. An Alberta producer who weighs his cows three times a year described the swings in April 2023:
"Our cows get weighed 3 times per year, weaning, before they calve and at processing in the spring. There are 200 to 400 Lb weight differences in weights of cows , depending on fill, how far along gestation is, cow condition scoring, how much they were pushed for winter gain before calving and how big a calf she weaned."
— Dirtfarmer1000, Alberta, April 2023 · AgTalk thread 1109155
When to body condition score cows
Mississippi State lists four times: at weaning, 60 days before calving, at calving and at the start of the breeding season. Virginia’s publication asks for at least three: weaning, 60 to 90 days before calving, and calving. Wyoming’s guide notes that scoring is often done about 100 days before calving and 60 days before breeding. The two that pay the most are weaning, when you can still sort cows into feeding groups with months to go, and 60 to 100 days before calving, when there is still time for what Virginia calls “emergency feeding.” If you preg check at weaning, write the score on the same sheet; our preg-checking guide covers that day.
Sorting at weaning is how producers we read turned scores into feeding groups. A northeast Kansas producer described his system for two-year-olds in February 2024:
"About 20-30% of the 2’s will loose condition in late lactation. These will stay in the high grocery pasture. The rest of the 2’s are moved to the mature cow pasture. Lastly, any extra thin cow, usually 2 head out of 60, will be sorted to the high grocery group at their weaning, if needed."
— Doug61, Eastern NE KS, February 2024 · AgTalk thread 1150081
Weaning date sets the clock. A HayTalk poster who calves in January described his schedule in October 2014:
"I wean calves in early October and begin calving in mid-January. This allows the cows 3 months to put on weight to attain a body condition score of about 5 or better before calving."
— vhaby, October 2014 · HayTalk thread 23836
Scores also guide day-to-day decisions through the winter. A northeast Iowa producer in his fourth winter of bale grazing described how he moves the fence in January 2026:
"Cows get access to 6-8 bales at a time (rule of thumb is 10hd/bale). Polywire gets moved to the next set based on bale utilization, weather, and body condition."
— McCurly, NE Iowa, January 2026 · AgTalk thread 1227558
Targets at calving and breeding
The targets are consistent across the publications we checked:
- Mature cows at calving: BCS 5 to 6 (Oklahoma State) or 5 (Mississippi State), and in a 5-to-7 range from the start of calving through breeding (Mississippi State).
- First-calf heifers at calving: BCS 6, because they are still growing (Oklahoma State and Mississippi State).
- After calving: keep the loss small. Oklahoma State’s advice is to minimize the weight and condition lost between calving and breeding, because drastic changes in late pregnancy and early lactation are “extremely difficult and costly to achieve.”
The reason is the calendar. A cow has to conceive within about 80 to 85 days of calving to calve on the same date next year, Oklahoma State notes, and thin cows start cycling later. The research summarized in the publications points the same way:
| Study (as cited) | What it found | Cited in |
|---|---|---|
| Six research herds in four states (Field and Sands) | About 60% rebred at BCS 4 or less at calving, about 80% at BCS 5, about 90% at BCS 6 or more (read from a chart) | Oklahoma State AFS-3283 |
| University of Wyoming, 60-day breeding season (Lake et al., 2005) | 88% pregnant at BCS 5 to 6; 69% at BCS 4 | Wyoming B-1294 |
| Days from calving to first heat (Houghton et al., 1990) | About 90 days at BCS 3, 70 at BCS 4, 60 at BCS 5, 52 at BCS 6 and 31 at BCS 7 | Wyoming B-1294 |
| Young cows, condition at calving and change after (Lalman et al.) | Predicted 103 days to first heat at BCS 5 holding condition, 131 at BCS 4 and 160 at BCS 3; gaining a full score after calving still left the BCS 4 cows at 115 days | Oklahoma State AFS-3283 |
| 81 heifers, Oklahoma (Bell et al.) | 91% pregnant if in adequate condition at calving and maintained; 67% if thin at calving and fed to gain; 36% if thin and only maintained | Oklahoma State AFS-3283 |
Mississippi State adds what thin cows give up besides rebreeding: they produce less colostrum, may not have the reserves for full milk production and are less likely to wean a live calf. Oklahoma State notes that cow condition also influences the calf’s ability to develop a strong immune system.
Producers we read agreed on the direction but not always on the number, especially for heifers. The Kansas producer quoted above aims for 5:
"They need to be in good body condition before they calve. Once she calves it is too late. Calving ease and bw is determined by genetics. Both maternal and paternal. That doesn’t mean you want them butterball fat but bc 5 is a good place to have them. Thin undernourished heifers have weak calves."
— kstate90, North Central Kansas, February 2024 · AgTalk thread 1150081
The northeast Kansas producer wants more going in, because he expects them to slip after calving (April 2023):
"At calving time, are the girls’ body condition score 6-6.5? My girls slip back to a 5, 40-50 days post calving mostly because this period is before green up."
— Doug61, Eastern NE KS, April 2023 · AgTalk thread 1106882
At breeding, the producers we read cared as much about the direction as the number. A northwest Iowa producer feeding silage, hay and distillers grains wrote in April 2025:
"My cows aren’t fat by any means. I like to see a rib or 2 for breeding. They stick better. But they have to have excellent feed to hold. ... My advice is test your feed."
— Massey1155, NW Iowa, April 2025 · AgTalk thread 1198365
And condition is not the only thing that decides a breed-up. A Nebraska producer, writing in October 2023 after his highest open rate ever, agreed on the timing but blamed water, not thin cows:
"body condition at calving and 90 days following probably has the most impact. More than just calories influences that. ... A couple years ago we had our highest open rate ever. Cows were a bit thin at pregcheck but not terrible, we’ve had them thinner at times and they bred fine."
— J HL, Nebraska, October 2023 · AgTalk thread 1133912
How much weight is one score?
Oklahoma State’s fact sheet, citing the 2016 National Academies beef requirements, puts one score at about 7% of the cow’s weight at BCS 5: a cow that weighs 1,200 pounds at BCS 5 should weigh about 1,284 pounds at BCS 6 and 1,116 pounds at BCS 4. Mississippi State’s table, adapted from the 2000 edition of the same requirements, shows the steps getting bigger as a cow gets fatter, from 70 to 140 pounds a score for cows in the moderate range. Virginia uses 75 to 100 pounds a score for a medium-framed open cow.
| Cow’s weight at BCS 5 | BCS 3 to 4 | BCS 4 to 5 | BCS 5 to 6 | BCS 6 to 7 |
|---|---|---|---|---|
| 1,000 lb | 60 lb | 70 lb | 80 lb | 100 lb |
| 1,200 lb | 72 lb | 84 lb | 96 lb | 120 lb |
| 1,400 lb | 84 lb | 98 lb | 112 lb | 140 lb |
Those pounds are body condition only. Virginia notes that a pregnant cow also gains about 100 pounds in the last trimester for fetal growth and uterine development, so a scale weight can rise while condition falls. That is one reason the publications rely on condition rather than weight.
Putting condition on thin cows
Time is the cheapest ingredient. The same 84 pounds is about 1.4 pounds a day if you have 60 days, 0.9 over 90 days and 0.6 over 150 days (XES arithmetic on Mississippi State’s 4-to-5 figure for a 1,200-pound cow; condition only). Virginia recommends sorting cows by score at or soon after weaning to allow 2 to 5 months of feeding before calving, and calls 90 to 100 days before calving the critical time to put condition back on a thin cow. Mississippi State lists early weaning as another option for thin cows; our weaning guide covers it.
Waiting until after calving costs more and works less well. In the Oklahoma heifer study above, heifers that calved thin and were fed to gain afterwards received about $141 of grain mix over 69 days and reached 67% pregnant; heifers that calved in adequate condition and were held there needed about $36 of cottonseed meal and reached 91%. Oklahoma State concluded that the improvement in the thin heifers “was not enough to offset the large investment in feed costs in most cases.” (Those are the study’s feed prices, not today’s.) An Alberta producer reached the same conclusion on his own place in December 2025; he scores on a 1-to-5 scale, so his “half a body condition score” is a bigger change than half a point on the 1-to-9 scale:
"I am also learning it is cheaper to maintain body condition than to let a cow go out and work for herself, loose 50 or 100 lbs and a half a body condition score then try to gain that back and then some in her most feed dense, nutrient needing time before calving."
— Dirtfarmer1000, Alberta, December 2025 · AgTalk thread 1221839
The hay test decides whether hay alone will do it
Mississippi State’s publication lists what a diet has to supply to move a mature cow from BCS 4 to 5 during the last 90 days of pregnancy. For a cow weighing 1,200 pounds at BCS 5, it is 23.5 pounds of dry matter a day at about 59% total digestible nutrients (TDN) and 7.4% crude protein: 13.9 pounds of TDN and 1.74 pounds of protein a day. Set that against what hay of different quality supplies at the same intake:
| Hay TDN (dry matter basis) | TDN eaten at 23.5 lb dry matter | Versus requirement |
|---|---|---|
| 48% | 11.3 lb | 2.6 lb short |
| 52% | 12.2 lb | 1.7 lb short |
| 55% | 12.9 lb | 1.0 lb short |
| 58% | 13.6 lb | 0.3 lb short |
| 60% | 14.1 lb | 0.2 lb over |
| 62% | 14.6 lb | 0.7 lb over |
The point is not the exact numbers; it is that hay testing in the low 50s for TDN will not put condition on a thin, late-pregnant cow by itself, while good hay near 60% can. Poorer hay is also eaten in smaller amounts: the South Dakota State figures in our hay-intake guide put dry mature cows at about 1.4% to 1.6% of body weight on poor forage, against 1.8% to 2.0% on medium-quality forage. Protein matters too: Wyoming’s rule of thumb is 7-9-11, about 7% crude protein for a dry cow in early pregnancy, 9% in late pregnancy and 11% in early lactation.
Producers closed the gap in different ways. A fall-calving herd in southeastern Idaho switches to its best hay early (March 2024):
"It is impossible for our cows to be on the gain that time of year but we do all we can to keep them from loosing weight. If I can maintain BCS I call it a win. I start feeding good quality hay around first of October to accomplish this and keep them on that kind of hay all the way thru breeding."
— ICC, southeastern Idaho, March 2024 · AgTalk thread 1151592
Near ethanol plants, distillers grains are a common answer. A HayTalk poster feeding cornstalks to cows wrote in March 2011:
"when feeding cornstalks (or very poor hay) protein is needed. If you have a ethanol plant that is close in proximity the Dry distillers grains are economical to feed and do a very good job of maintaining body condition on the cows. Typically I will feed about 5 to 8 lbs of distillers per head (5 gal pail = 25 lbs)."
— ekyllo, March 2011 · HayTalk thread 14441
Others reported corn silage (a northwest Wisconsin producer: it “fixes the skinny problem real quick”), oat hay, or a few pounds a day of corn or a commodity mix. Skimping can backfire. A Nebraska producer described supplement advice he once followed for fall-calving cows on stalks, in March 2025:
"In order to make the protein supplement even remotely cost effective he lowered the lbs/day so low that it wasn’t even close to enough for a lactating cow with a calf. After the cows lost so much body condition and the calves were small at weaning I realized that I had to learn it on my own."
— Bluedog, Nebraska, March 2025 · AgTalk thread 1194933
Which supplement makes sense depends on price and on what the hay test shows; our guides to distillers grains, whole cottonseed, corn silage and protein tubs and range cubes cover the options.
Fat cows cost money too
Condition can be too high as well as too low. Virginia lists BCS 8 to 9 cows as the most costly to maintain, with more calving difficulty, impaired mobility, and failure to cycle and conceive; it adds that two-year-olds at BCS 8 to 9 may have trouble calving because of fat in the pelvic area. Mississippi State notes that over-conditioning is expensive and can bring calving problems and lower feed intake early in lactation. Virginia’s advice is to use the same 90 to 100 days before calving to restrict the feed of fat cows, and it warns against over-feeding cows already in good condition when only part of the herd needs extra energy.
A range rancher put condition, thin or fat, at the top of his list when another poster asked why breeding was dragging out (June 2023):
"Just random thoughts, if cows are dragging out getting bred it’s most likely you caused it. From lack of nutrition, or too much i.e. too fat of cows. ... The big problem was those cows were too fat, it was costing 10% opens as well in that herd. I changed cow body condition, it tightened up calving window."
— Russ In Idaho, June 2023 · AgTalk thread 1115147
A southwest Missouri producer saw it in heifers held over to calve later (August 2023):
"I was wanting some spring calving cows so I just held some heifers over. Lost too many calves. I think the heifers got too fat."
— 68milkman, Monett Missouri, August 2023 · AgTalk thread 1127265
Limiting feed was the fix producers described. A Nova Scotia producer cut his cows back during two winters when he was low on feed (January 2020):
"Used to keep the feeders full and the cows fat as ticks, and they’d still swarm the tractor every feeding, like they hadn’t eaten in a week.. I was low on feed the last 2 winters, so I cut them back.. They maintained ok body condition, but didn’t carry much extra weight.."
— Supa Dexta, NS Canada, January 2020 · AgTalk thread 898156
“Too fat” is also a matter of opinion. A southwest Wisconsin producer whose cows another poster kept calling too fat answered in March 2025:
"I think they look great especially having gone through this winter. My cows have never had a mouthful of silage. ... Are they TOO fat? Who knows, who cares, as long as they work in my system."
— Jim, Driftless SW Wisconsin, March 2025 · AgTalk thread 1193211
The publications’ range does run to 7 through breeding, and a fleshy cow that calves every year on forage alone is doing her job. The cost shows up when cows are fat because they are overfed, not because they are easy keepers.
Why cows lose condition on hay
Oklahoma State describes a score as “a snapshot in time” of the balance between recent nutrient supply and requirements, and calls body condition a good reflection of the match or mismatch between a cow’s genetics and the forage and management system. When condition drops through the winter, these are the usual suspects:
- Hay that is poorer than it looks. Late-cut or weathered hay can look fine and test poorly; Wyoming’s guide notes that dormant winter range near Laramie has tested as low as about 3% crude protein and 40% TDN in January. Test before you rely on it.
- Toxic fescue. Endophyte-infected tall fescue came up in several of the threads we read.
- Cold, wind, wet and mud. Energy needs rise below the lower critical temperature; our windbreak and bedding guides cover the numbers.
- A calf at side in winter. Fall calvers nurse through the coldest months; our guide to fall vs spring calving covers the extra feed.
- Teeth and age. Broken-mouthed and old cows can go downhill fast.
- Competition at the feeder. Timid and young cows can lose out at a crowded feeder, one reason producers we read ran thin cows and first-calf heifers as a separate group.
- Health. When a cow stayed thin on good feed, posters’ suspicions turned to worms and to diseases such as Johne’s disease or anaplasmosis, questions for your veterinarian.
Two HayTalk posters described hay that did not feed the way they expected. One in August 2015:
"I almost starved some cattle the winter before last by feeding infected fescue. I baled a beautiful place on shares and bought the owner’s share. ... My cows lost condition very fast. I had the hay tested and it was 100% infected. We no longer bale that field."
— Tim/South, August 2015 · HayTalk thread 26683
Another, after a wet year of over-ripe hay, in June 2019:
"We experienced problems with cows maintaining and the losing condition even after a lot of fall grazing to lead another neighbor and myself to think the hay and grass,although abundant,lacked a lot of food value.Only after we started supplementing a grain mix did our cows start to improve."
— jr in va, June 2019 · HayTalk thread 92772
A northeast Missouri producer made the fescue point in November 2025:
"Once cows get thin on fescue that they don’t really do good on, it’s darn hard to bring them back to breeding shape."
— oldtiger, NEMO, November 2025 · AgTalk thread 1220737
On cold, a Manitoba producer’s advice in December 2022 was to feed ahead of the weather:
"try to feed for two days from now--if cows have lost condition due to cold and it’s still that cold, you can expect at least two more days of condition loss even if you act right away"
— northerngrazer, MB, Canada, December 2022 · AgTalk thread 1091278
And on age, the same Manitoba producer, about a cow of about 20 whose calf weaned 50 pounds lighter, in March 2023:
"When it comes to longevity, my biggest suspicion is that it just comes down to good teeth--a cow can have all the right parts to last a long time but when her teeth go on her then she just falls apart in a matter of months."
— northerngrazer, MB, Canada, March 2023 · AgTalk thread 1103510
First-calf heifers and bulls
Heifers carrying their first calf need more than mature cows because they are still growing, which is why both Oklahoma State and Mississippi State set their calving target at BCS 6. Our replacement heifer guide covers how to feed them through the winter. Bulls are scored on the same 1-to-9 scale: Mississippi State targets BCS 6 at the start of the breeding season, and North Dakota State University Extension recommends 5.5 to 6.5 before breeding. Some newly bought bulls arrive fatter than that; our guide to buying a bull covers how to bring a sale bull down to breeding condition on forage.
A body condition worksheet for this winter
- Score every cow at weaning or preg check. Write the score next to the tag number, the pregnancy call and the expected calving date.
- Sort into groups. For example: BCS 4 or less plus first-calf heifers; BCS 5 to 6; BCS 7 or more.
- Test the hay you will feed each group. Look at TDN and crude protein on a dry matter basis.
- Work out the gain. Pounds per score (about 7% of the cow’s BCS-5 weight) times the scores needed, divided by the days left before calving. Remember the calf’s growth in the last trimester comes on top.
- Match hay and supplement to the gap, with a nutritionist or Extension specialist, and give the thin group the best hay.
- Re-score 60 to 100 days before calving and adjust while there is still time.
- Score again at calving and at breeding, and keep the records; cows that come up thin every year are culling candidates.
Frequently asked questions
What is a good body condition score for beef cows?
On the 1-to-9 beef scale, aim for 5 to 6 in mature cows at calving and 6 in first-calf heifers, the targets Oklahoma State and Mississippi State Extension give, and keep cows in the 5-to-7 range through breeding. Cows that calve at 4 or less rebreed later and less often, and cows at 8 or 9 cost more to feed.
How much weight is one body condition score?
About 7% of the cow’s weight at BCS 5, according to Oklahoma State: roughly 84 pounds for a cow that weighs 1,200 pounds at BCS 5. Mississippi State’s table runs from 70 to 140 pounds per score for cows in the moderate range, because bigger and fatter cows need more weight to move up a score.
When should you body condition score cows?
At weaning, 60 to 100 days before calving, at calving and at the start of breeding. Weaning matters most, because you can still sort thin cows into a better-fed group with months to go; the score before calving tells you whether winter feeding is working while there is still time to change it.
Can you put condition on a cow after she calves?
Some, but it is expensive and does not fully work. In an Oklahoma study, heifers that calved thin and were fed about $141 of grain mix afterwards reached 67% pregnant, against 91% for heifers that calved in good condition and were maintained on about $36 of cottonseed meal, at the study’s feed prices, not today’s. Fix condition before calving.
Is body condition scored 1 to 5 or 1 to 9?
U.S. beef cattle are scored 1 to 9, with 1 emaciated and 9 obese. Dairy cows use a 1-to-5 scale, the University of Wyoming notes, and some Canadian beef producers we read also talk in fifths, so check which scale a number comes from before you compare it with a target.
The bottom line on body condition scores
A body condition score is a free, five-second check that tells you whether your hay and supplement are doing their job. Score at weaning, sort the thin cows and first-calf heifers into their own group, test the hay, and put condition on in the months before calving, when it is cheapest; aim for 5 to 6 in mature cows and 6 in first-calf heifers at calving, and keep the loss small until breeding. Then score again before calving, while there is still time to change course.
Hay that tests well only helps if it keeps its quality until you feed it; our guide to storing net-wrapped bales outside covers how to keep storage losses down. XES Extreme bale net wrap was tested by DLG (Report 7439), which rated its edge-to-edge bale coverage as good in practical use.
Research note: We read 865 posts from 223 archived AgTalk, HayTalk and TheFarmingForum discussions that mention body condition, condition scores or thin and fat cows (the posts that mention them, the post on either side, and every post in the 5 discussions with the topic in the title, out of 4,183 posts in those discussions; posts from February 2010 to May 2026; 203 discussions started in 2022 or later), and two readers coded about 300 of those posts as relevant to beef cow and heifer condition; posts about slaughter cattle (“fat cows” as a market class), dairy cows, sheep, goats and horses were set aside. Quotes are verbatim and attributed to the poster named; places are as the posters gave them, and dates are the month of the post. Producer reports are individual experiences, not research results or recommendations. Figures marked as XES arithmetic use the assumptions stated with them. This page is general information, not a ration or veterinary advice.
